Would the person feel anything? Presumably the electricity would flow through the metal as path of least resistance?
You don't shock the person.
You heat up the metal until it burns them.
I used to burn paper with a 9 volt and a paperclip. Good times
It's a short, the metal would heat up extremely fast and burn.
You can start a fire with a 9v battery and some steel wool.
Why would you spread incorrect information so confidently? You're absolutely wrong. A 9 volt will get hot in a few seconds when shorted.
I used to put small coins on the terminals til they got super hot, then drop the coin on the desk in front of them. When they go to pick it up, it burns them. Peak comedy.
Put an AA battery in some aluminium foil, much can happen with even such a small battery
I mean, someone with a septum piercing could confirm this pretty fast.
Pretty sure it would be nice and toasty inside 30 seconds.
Yes, it would heat up. It would not be pleasant
They prob wouldn't get shocked but the ring and battery will get very hot very quick as there i pretty much no resistance wich means there is a lot of current flowing.
Someone else in the comments claimed to have calculated a resistance of 0.2 ohms.
I=U÷R
9V ÷ 0.2Ω = 45A
45 amps is a lot of current to flow through a nose ring. I don't know how much that is in heat but i'd expect you to get burned from it
You won't get more than a few mA out of an alkaline, but heat does build up. (Internal resistance)
A NiMH on the other and can give over 10 amps. They're a seriously risky thing to leave around loose metal bits. Or attached to thin wires.
Definitely won’t get shocked. I’ve run estim through nipple piercings and no shocks
Just put a 9volt in your pocket with some change
No, 9v batteries have almost no shock to them. Put one on your tongue or lick your finger and touch the terminals. You’ll feel nothing.
Dry skin is hundreds of thousands of ohms. Even wet skin has pretty good resistance. When you touch a 9v to your tongue, you're starting to mess around with lower resistance flesh, it is definitely not a comfortable thing to do.
The metal ring doesn't do anything to move more electricity into your body, but it soaks every electron the battery can push and turns it into heat. Best I can figure it would amount to a few watts, which would be toasty if you were holding it between your fingers. The septum is a thin piece of flesh, I think it would sauté pretty quickly.
Thank you, I appreciate the explanation. Being fairly physics ignorant I was wondering about that.
I mean, if you lick a 9v you definitely feel something. It's not painful, but it's not natural or pleasant either.
Can confirm. Used to lick them as a kid
If those are separate pieces of metal embedded in the skin, they will feel something. If it’s just an incomplete ring, it will draw so much current that the battery voltage drops too low to feel anything but the heat.
Another confidently incorrect person
What? They are clearly just screwing around man.
Woosh I guess
But it'd probably get really hot
